Description

Technical Field

[0001] This utility model relates to the field of air purification technology, and in particular to an air purification device for agricultural greenhouses. Background Technology

[0002] As modern agriculture develops towards facility-based and intelligent systems, agricultural greenhouses, as the core carriers of efficient agricultural production, have become crucial for ensuring crop growth quality through their internal environmental control technology.

[0003] Traditional air purification devices often use a combination of fixed air inlets and exhaust fans, resulting in a single airflow path that makes it difficult to fully cover the greenhouse space. This leads to the accumulation of harmful gases (such as ammonia and carbon dioxide) and dust in localized areas, affecting crop photosynthesis and respiration. Existing fertilizer spraying equipment mostly relies on static nozzles or simple rotating mechanisms, which have limited spraying range and are easily affected by fertilizer sedimentation, resulting in excessively high or insufficient fertilizer concentrations in localized areas. Therefore, this utility model proposes an air purification device for agricultural greenhouses. Utility Model Content

A sealing ring is provided on the inner side of the air extraction pipe. An air inlet pipe is rotatably connected to the inner side of the air extraction pipe. Multiple sets of air holes are opened on the outer side of the air inlet pipe. The air inlet pipe has an E-shaped design.

[0013] This device features an innovative design that links motor drive with air pump, enabling simultaneous operation of air purification and fertilizer spraying. It ensures flexible positioning of the air intake hopper within the greenhouse, expanding the air intake range. Through the meshing of the first and second bevel gears, the air intake pipe rotates within the extraction pipe, allowing the air intake hopper to dynamically capture air from different directions, effectively expanding the intake range and reducing dead zones. The purified air is filtered by an activated carbon adsorption tank and then divided into two paths: one path blows dust off the blade surface through the lower end of the exhaust pipe, preventing fertilizer adhesion from affecting rotational efficiency; the other path cleans impurities from the surface of the first bevel gear through the first exhaust pipe, preventing wear on transmission components due to dust accumulation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1 - Figure 5 An air purification device for agricultural greenhouses is shown, including a mounting frame 1. A rack 2 is fixedly connected to the upper end of the mounting frame 1. A moving mechanism 3 is installed at the upper end of the rack 2. The moving mechanism 3 includes a fixed frame 31. A circulation mechanism 4 is installed at the upper end of the fixed frame 31. The moving mechanism 3 includes a mounting block 36. A discharge mechanism 5 is installed on the inner side of the mounting block 36.

[0023] In this embodiment, the moving mechanism 3 includes a fixed frame 31 fixedly connected to the mounting block 36. A motor 33 is mounted on the rear end of the fixed frame 31. A first rotating shaft 32 is rotatably connected to the inner side of the fixed frame 31. The output shaft of the motor 33 is fixedly connected to the first rotating shaft 32. A first gear 34 is fixedly connected to the outer side of the first rotating shaft 32. The outer side of the first gear 34 meshes with the rack 2. A first bevel gear 35 is fixedly connected to the front end of the first rotating shaft 32.

[0024] Specifically, the motor 33 serves as a power source, and its output shaft drives the first rotating shaft 32 to rotate. The first rotating shaft 32 not only transmits power but also meshes with the rack 2 through the first gear 34 fixedly connected to the outside, thereby converting the rotational motion into the linear movement of the mounting block 36, which in turn drives the entire device to move along the rack 2 direction within the greenhouse. The first bevel gear 35 at the front end of the first rotating shaft 32 is used to mesh with the second bevel gear 53 in the discharge mechanism 5 to transmit power to drive the discharge mechanism 5 to work.

[0025] In this embodiment, the circulation mechanism 4 includes an air pump 41 mounted on the upper end of the fixed frame 31. The air pump 41 is fixedly connected to an air extraction pipe 42. A sealing ring is provided on the inner side of the air extraction pipe 42. An air inlet pipe 43 is rotatably connected to the inner side of the air extraction pipe 42. Multiple sets of air holes 44 are opened on the outer side of the air inlet pipe 43. The air inlet pipe 43 is E-shaped. The two far apart lower ends of the air inlet pipe 43 are fixedly connected to air inlet buckets 45.

[0026] Specifically, the air pump 41 serves as the core power source for air purification and circulation, drawing air through the air extraction pipe 42; the sealing ring on the inner side of the air extraction pipe 42 ensures airtightness and prevents air leakage; the air inlet pipe 43 rotates inside the air extraction pipe 42, and its E-shaped design and multiple sets of air holes 44 on the outside allow air to be drawn in from different angles, and the air intake range is expanded through the air intake hopper 45.

[0027] In this embodiment, an exhaust pipe 46 is fixedly connected to the output port of the air pump 41, an activated carbon adsorption tank 48 is provided on the outside of the exhaust pipe 46, and a first exhaust pipe 47 is fixedly connected to the bottom of the activated carbon adsorption tank 48 on the outside of the exhaust pipe 46.

[0028] Specifically, the exhaust pipe 46 discharges the purified air, the outer activated carbon adsorption tank 48 is used to further filter the air, and the lower first exhaust pipe 47 is used to connect to the discharge mechanism 5 to achieve synergy between air purification and fertilizer spraying.

[0029] In this embodiment, the discharge mechanism 5 includes a storage tank 51 fixedly connected to the mounting block 36. The outer side of the storage tank 51 is fixedly connected to the first air outlet pipe 47. The outer side of the storage tank 51 near the lower end is fixedly connected to the exhaust pipe 46. The inner side of the storage tank 51 is rotatably connected to a second rotating shaft 52. The upper end of the second rotating shaft 52 is fixedly connected to the air inlet pipe 43. The outer side of the second rotating shaft 52 is fixedly connected to a second bevel gear 53. The outer side of the second bevel gear 53 is meshed with the first bevel gear 35.

[0030] Specifically, the storage tank 51 is used to store fertilizer. Its outer side is connected to the exhaust pipe 46 and the first air outlet pipe 47. The exhaust pipe 46 not only discharges purified air, but also introduces part of the purified air into the storage tank 51 through its connection with the storage tank 51, which is used to clean impurities on the surface of the first bevel gear 35 and blow away dust adhering to the surface of the blade 56.

[0031] In this embodiment, a stirring rod 54 is fixedly connected to the lower part of the second bevel gear 53 on the outer side of the second rotating shaft 52, a feed hole is opened on the outer side of the second rotating shaft 52, an electromagnetic spray head 55 is installed at the lower end of the second rotating shaft 52, and a blade 56 is fixedly connected to the outer side of the second rotating shaft 52 near the lower end.

[0032] Specifically, the second bevel gear 53 meshes with the first bevel gear 35 in the moving mechanism 3, receives power, and drives the second rotating shaft 52 to rotate; the stirring rod 54 is fixed to the outside of the second rotating shaft 52 and is used to stir the fertilizer in the storage tank 51 to prevent sedimentation; the electromagnetic spray head 55 is installed at the lower end of the second rotating shaft 52 and is used to spray the fertilizer evenly; the blade 56 is fixed to the outside of the second rotating shaft 52 near the lower end. Its rotation not only helps to stir the fertilizer, but also disperses the fertilizer droplets when the fertilizer is sprayed, improving the uniformity of spraying. At the same time, the purified air is blown through the first air outlet pipe 47 to sweep the surface of the blade 56 to prevent fertilizer residue.

[0033] Working principle: When using this equipment, the mounting frame 1 is fixed inside the greenhouse. The motor 33 at the rear end of the mounting frame 31 is started. The motor output shaft drives the first rotating shaft 32 to rotate, which drives the first gear 34 to mesh with the rack 2, so that the mounting block 36 moves linearly along the rack 2. At the same time, the air pump 41 is started to start the air purification and fertilizer spraying process. Air enters the air inlet pipe 43 through the air inlet hopper 45, flows into the air extraction pipe 42 through the air holes 44 on its side wall, and is finally sucked in by the air pump 41. The first bevel gear 35 at the end of the first rotating shaft 32 meshes with the second bevel gear 53, driving the second rotating shaft 52 to rotate. This causes the air intake pipe 43 to rotate within the air extraction pipe 42, making the air intake bucket 45 rotate synchronously and expanding the air intake range. The second rotating shaft 52 synchronously drives the stirring rod 54 to stir the fertilizer in the storage tank 51 to prevent sedimentation. The fertilizer is also stirred by the rotation of the blades 56. When the electromagnetic spray head 55 is activated, the fertilizer is sprayed out through the spray head and dispersed by the high-speed rotating blades 56, achieving uniform spraying. The purified air is output to the exhaust pipe 46 by the air pump 41. After being filtered by the activated carbon adsorption tank 48, it is divided into two paths: one path is discharged from the lower end of the exhaust pipe 46 to blow away the dust attached to the surface of the blades 56, and the other path is discharged from the first air outlet pipe 47 to clean the impurities on the surface of the first bevel gear 35.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
